WHY?
The train keeps going, whether people walk on the rails or not. No time to lose. The British originally constructed the railway network, forming the arteries of the country. A much better means of travel than by car.
WHAT?
I was allowed into this second-hand American locomotive to sound the horn. Big fun! When I took this picture later, the passengers sitting illegally on the train’s nose weren’t quite so amused, and threw plastic bags filled with water at me.
